Helheim's Gate

Helheim's Gate is one of four locations of Return to Dragon Island Expansion, which can be accessed via Membership or purchase it with 1,250 Gems.

It's by going through Helheim's Gate that you can find Dragon Island, during the mission Dragon Island.
Helheim's Gate seems to have a wide open space, unfortunately, it's not the case. Instead, Helheim's Gate is filled with numerous Invisible Walls and the Ocean Currents that can drag you and make it difficult to overcome; with both of these, it can be quite hard to navegate since it's easy to be stuck between an Invisible Wall and an Ocean Current.

An invisible wall stopping the player from going up

Ocean Currents pushing the player into a corner filled with invisible walls (in both above and behind)

In certain areas, there will be Ocean Currents that will either push the player to the opposite direction or to the sides
